示例1: if
void
wxHeaderCtrlBase::DoResizeColumnIndices(wxArrayInt& colIndices, unsigned int count)
{
// update the column indices array if necessary
const unsigned countOld = colIndices.size();
if ( count > countOld )
{
// all new columns have default positions equal to their indices
for ( unsigned n = countOld; n < count; n++ )
colIndices.push_back(n);
}
else if ( count < countOld )
{
// filter out all the positions which are invalid now while keeping the
// order of the remaining ones
wxArrayInt colIndicesNew;
colIndicesNew.reserve(count);
for ( unsigned n = 0; n < countOld; n++ )
{
const unsigned idx = colIndices[n];
if ( idx < count )
colIndicesNew.push_back(idx);
}
colIndices.swap(colIndicesNew);
}
//else: count didn't really change, nothing to do
wxASSERT_MSG( colIndices.size() == count, "logic error" );
}示例2: MoveColumnInOrderArray
/* static */
void wxHeaderCtrlBase::MoveColumnInOrderArray(wxArrayInt& order,
unsigned int idx,
unsigned int pos)
{
const unsigned count = order.size();
wxArrayInt orderNew;
orderNew.reserve(count);
for ( unsigned n = 0; ; n++ )
{
// NB: order of checks is important for this to work when the new
// column position is the same as the old one
// insert the column at its new position
if ( orderNew.size() == pos )
orderNew.push_back(idx);
if ( n == count )
break;
// delete the column from its old position
const unsigned idxOld = order[n];
if ( idxOld == idx )
continue;
orderNew.push_back(idxOld);
}
order.swap(orderNew);
